Adjustment of set pressure:
Turn the relief valve lock nut (2) to the left to loose it, and then turn the pressure adjustment nut (1) to the right to tighten it, in order to

The air compressors are equipped with a safety valve to prevent too high pressure in the air reservoir, posing a hazard. The safety valve has
been adjusted according to the design specification of “pressure vessel” at the factory. Please do not adjust it arbitrarily. If you need to adjust
it, please inform our service department or the dealer. Normally, pull the relief ring at least 5 times every week to check that the safety valve
is functioning properly. (Refer to Fig. C)

3. Pay attention to abnormal sound, vibration or implausibly high heat during operation.
B. Weekly maintenance:
